TJD 9167 = June 29, 1993
TJD 9168 = June 30, 1993

Because of apparent errors or other problems in changing the gains 
for Spectroscopy Detectors 1, 3, 4, 6 (SD 1, SD 3, SD 4, SD 6), it 
was not possible to calibrate those detectors during the interval

   TJD/SoD:   9167/53831 - 9168/79575.

Therefore, no records exist in the spectral calibration history
file for SD 1, SD 3, SD 4, and SD 6 for the above interval.

The end of the interval was determined by when the commands to
correct the high voltages were executed.  (Also, commands were sent
to adjust the gains for SD 1,6 at TJD/SoD 9167/85403.)

No triggers occurred during the interval.
